Dust Removal

One way may be to use better furnace filters.  Use Merv 11 to 13.  Also, you can build inexpensive high quality filters out of a box fan and Merv filter. 

Yes, compressed air, but it can lead to short-term condensation, so make sure your gear is UNPLUGGED before blowing any air cans..  Let it sit for 20 minutes before plugging back in. 

Thanks for all the suggestions. . . quite a range, here !  

Sneak some speed bumps on the road about 50' on either side of your home overnight and feign innocence when asked about it.

Hah!  I really wish I could get away with that -- we get mighty sick of the jerks who use our private road as a dirt-bike race course. But given the attitudes and personalities involved, it could lead to armed conflict, so best not.

I really feel for you, having to live (survive?) under those circumstances. We were making such progress as a species only to have the bar lowered.

All the best,
